PACKIN'G JOINT.

171 all whom it may concern:

Be it known that I, PHILIP C. TRAVER, a citizen of the United States, residing at Far Rockaway, Queens county, State of New 5 York, have invented certain new and useful Improvements in PackingJoints, of which the following is a specification sufficient to enable others skilled in the art to which the invention 'appertains to uia-ke and use the :0 same. e

My invention relates to means for rendering joints between two parts to be coupled together air and water tight; and the invention consists in the special arrangement and :5 construction of parts hereinafter described and claimed specifically.

In the accompanying drawings, Figures 1 and 2 represent, respective] y, central sections of two applications of my improved form of so packing-joint, the one representing a pipe or hose coupling and the other a bottle-seal. Fig. 3-is a section of the socket-piece, showing one of the bayonet-slots; Fig. 4, an end view of the socket-piece; Fig. 5, a transverse 95 section on plane of line 5 5, Fig. 1; Fig. 6, a transverse section on plane of line 6 6, Fig.

1'; Fig. 7, an end view of the coupling-piece; Fig. 8, an end elevation of the same; Fig. 9,

. a section upon plane of line 9 9, Fig. 7; Fig. 3e 10, an elevation of the coupling-piece shown in Fig. 2; Fig. 11,a section of the elastic sleeve.

A and B, respectively, represent the two parts to be coupled together-as, for instance, two sections of hose or piping, as in Fig. 1,

35 or a cork and bottle-neck as in Fig. 2.

either case the female part or socketpiece A is formed with an annular-recess a and with bayonet slots or recesses (3, each formed of a main channel or way c, a lateral extension 0 c, and a mortise as shown clearly in Figs.

inthe shape of an inwardly-projecting am lar flange adapted to fit in the annular rec a in the socket-piece A, the spiral spring being interposed bet-ween the facev of coupling piece and the said annular flange of rubber or other elastic packing mater. A convenient way of attaching the sle: D and the spring E to the face of the cor ling-piece B is to turn in the edge (I of sleeveD and interpose such edge betw the face of the coupling-piece and the all ting convolution e of the spring, which n be secured to the couplingpiece B by a suitable means, as by turning over a. flat b, as indicated in Figs. 1 and 2, the edg of the sleeve D being tucked 'in between spring and the opposed face of the coupling In use the outlet the oupling-piece I.

, that I claim as my invention, and dc to secure by letters Patent, is-

1 a 'oiut, the combination spring together with said coiled spring, fer the purpose and substantially in the manner deacz'ibed.
